Patent number: 11680862Abstract: A gauge pressure transducer assembly having anti-icing features to allow for easy drainage of fluids to prevent pooling and icing. The assembly can include a header having one or more atmospheric ports extending therethrough, a differential sensing element mounted to the header, a header cap attached to at least a portion of the header, a gauge adapter attached to the header and in communication with the one or more atmospheric ports of the header, an elongated tube attached to the header cap, and a front port attached to the elongated tube.

Patent number: 11668616Abstract: A stretchable sensor skin is provided, which is a soft tactile sensor sleeve that can cover large areas of a robot, and is both low-cost and robust. It is made of elastomer molded pouches (referred to as sensor taxels) that when contacted transmit pneumatic pressure to off-board barometric sensors, via stretchable channels. The entirely soft makeup of the sleeve makes it highly conformable to 3D curved geometries of a robot. The stretchable channels mean that it can cover joints without wiring getting caught. The stretchable rubber channels are also inherently more robust than stretchable conductor approaches, and the skin lacks fragile soft-rigid interfaces that has plagued many other sensor skins. The fact that there are no conductive components also makes the skin easy to sanitize and waterproof.Type: GrantFiled: March 22, 2022Date of Patent: June 6, 2023Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Alexander M.
